PATENT OFFICE PHILIP A. (FERGUSON, OF MEDFORD, MASSACHUSETTS.

WATER-GAGE.

Specification of Letters Patent.

Patented Oct. 31,- 1916.

Application filed December 28, 1911. Serial No. 667,468.

To all whom it on ag concern:

Be it known that I. Prune A, 'JERGUSON, of Medford, in the county of Middlesex, and in the State-of Massachusetts, have invented a certain new and useful Improvement in Water-Gages, and do hereby declare that the following is afull, clear, and exact description thereof.

My invention relates to water gages and has for its object to provide a water gage in which the parts may be assembled or disassembled readily and quickly.

' A further object of my invention is to provide a water gage in which the glass or the packings may be renewed without disconnecting any of the boiler connections.

One embodiment of my invention is illustrated in the accompanying drawings, in

' which:

Figure 1 is a front elevation; Fig. 2 a central vertical section; and Fig. 3 a central horizontal section.

Although the apparatus chosen to illustrate my invention embodies the best mode in which I have contemplated applying the principle thereof, it is to be understood that such apparatus is to be regarded as typical only of many possible embodiments and modifications.

In the embodiment illustrated in the drawings, an indicating tube is shown of any desired type, in the present instance comprising a conduit A having a slot formed in its face which is closed by a glass C. The conduit may be connected directly to the boiler in any desired manner as by connections B and B. In this type of indicating tube, the joint between the conduit and glass is made steam-tight and watertight by a gasket D. The indicating tube is inclosed by a casing E preferably having inturned edges at its front comprising lips F adapted to bear on the front of the indicating tube. Upper and lower portions 6' and 6" respectively, also may be provided on casing E if desired, to bear onthe front of said and to be withdrawn from the indicating tube.

When it is desired to assemble the watergage illustrated by the drawings (it being assumed that conduit A already is connected to the boiler), it is necessary only to place packing D, glass C, and cushion G in position, inclose them with casing E, position plate H, and tighten set screws I. The pressure at the different parts of the gage may be adjusted by said set screws I to insure tight connections Without danger of breakage. In case of a broken glass or of ineffective packings, set screws I may be loosened, plate H and casing E removed, the necessary parts repaired or renewed, and the gage assembled as before. 1 Having described one embodiment of my invention, what, I claim and desire to protect by Letters Patent is:

1. In a water gage, an indicating tube comprising a plurality of parts, and means to maintain said parts in operative position comprising a casing adapted to bear on the front of said tube, a plate detachably engaging said casing, and means mounted on said plate and adapted to bear on the back of said tube '2. In a water gage, an indicating tube comprising a plurality of parts, and means to maintain said parts inoperative position comprising a casing adapted to bear on the front of said tube, a plate engaging said casingand vertically detachable therefrom,

and means mounted on said plate and adapted to bear on the back of said tube.

\ 3. In a water gage, .an indicating tube comprising a plurality of parts, and means to maintain said parts in operative position comprising a casing adapted to bear on the front of said tube, a plate detachably engaging said casing, and means comprising set screws mounted on said plate and adapted to bear on the back of said tube.

a. In a water gage, a conduit having a slot formed in its face, a glass to close said slot, a casing adapted to bear on the front of said glass, a plate detachably engaging said casing, and means mounted on said plate and bly forming a vertical sliding engagement. adapted to bear on the back of said conduit.

'5. In a water gage, an indicating tube comprising a plurality of parts, and means to maintain said parts in operative position comprising a casing adapted to bear on said tube, and a plate having means to bear against said tube, said casing and said plate having vertical flanges adapted to interlock.

6. In a water gage, an indicating tube comprising a plurality of parts, and means to maintain said parts in operative position comprising a casing adapted to bear on the front of said tube and provided with flanges,

and/a plate carrying devices adapted to'bear on the backof said tube and provided with flanges to engage with said casing flanges.

In a water gage, an indicating tube comprising a plurality of parts, and means to maintain said parts in operative position comprising a casing adapted to bear against said tube and provided with flanges separated by a space sufliciently large to pass said tube, a plate adapted to engage said flanges, and set screws carried by said plate and adapted to engage said tube.

8. In a water gage, an indicating tube comprising a plurality of parts, and means to maintain said parts in operative position comprising a casing adapted to bear against said tube and provided with flanges separated by a space sufiiciently large to pass said tube, a plate adapted to engage said flanges, and set screws carried by said plate and adapted to engage said tube, said casing also having upper and lower front portions adapted to engage the front of said tube.

9. In a water gage, an indicating tube comprising a plurality of parts, and means to maintain said parts in operative position comprising a casing adapted to bear on the front of said tube, a plate carrying devices adapted to bear against said tube, said casing and said plate having vertical flanges adapt ed to interlock; and boiler connections directly connected to said tube.

10. In a water gage, an indicating tube comprising a plurality of parts, and means to maintain said parts in operative-position comprising a casing adapted to bear against said tube and provided with flanges separated by a space sufficiently large to pass said tube, a plate adapted to engage said flanges, set screws carried by said plate and adapted to engage said tube; and boiler connections directly connected to said tube.

11. In a water gage, an indicating tube comprlsing a plurality of parts and means to maintain said parts in operative position comprising a casing adapted to bear against said tube and provided with flanges separated by a space sufficiently large topass said tube, a plate adapted to engage said flanges, set screws carried by said plate and adapted to engage said tube, said casing having upper and lower front portions adapted to inclose said tube; and boiler connections directly connected to said tube.

12. In a water gage, an indicating tube comprising a plurality of parts, and means to maintain sald parts in operative position comprising a casing provided with inturned edges at thefront and inturned flanges at the rear, the space between said edges being sufficiently small to enable said edges to engage said tube, and the space between said flanges being sufficiently large to enable said flanges to pass said tube, and means to secure said casing to said tube.

13. In a' water gage, an indicating tube comprising a plurality of parts, and means to maintain said parts in operative position comprising a casing provided with inturned edges at the front and inturned flanges at the rear, the space between said edges being sufliciently small to enable said edges to engage said tube, and the space between said flanges being sufliciently large to enable said flanges to pass said tube, and means detachably to secure said casing to said tube.

In testimony that I claim the foregoing 'I have hereunto set In hand.-
